         5 . The apparatus for sharing and storing mass video data of  claim 3 , wherein the mass video data share, storage and management component comprises: 
 a share and storage component interface enabling the map viewer and the video viewer to be accessible to the component through one common interface;    a share and storage information manager for storing and managing share and storage information of the video data corresponding to the spatial geographic information;    a query processor for processing video data-related query from the map viewer and the video viewer; and    a communication module for transmitting query and performed result of the query between the elements of the client and the databases of the server.    
     
     
         6 . The apparatus for sharing and storing mass video data of  claim 4 , wherein the query processor comprises: 
 a query analyzer for determining video database for query to be actually performed on by referring to the share and storage information, collecting the performed result in each database, and planning for post-process for achieving the same results as in a single database;    a query separator for separating query such that a corresponding query is processed in each video database according to query analysis result by the query analyzer; and    a query executor for transmitting each query separated by the query separator to corresponding video database to perform the query, and performing the post-process achieved from the query analyzer to achieve final results.    
     
     
         7 . The apparatus for sharing and storing mass video data of  claim 5 , wherein the query processor comprises: 
 a query analyzer for determining video database for query to be actually performed on by referring to the share and storage information, collecting the performed result in each database, and planning for post-process for achieving the same results as in a single database;    a query separator for separating query such that a corresponding query is processed in each video database according to query analysis result by the query analyzer; and    a query executor for transmitting each query separated by the query separator to corresponding video database to perform the query, and performing the post-process achieved from the query analyzer to achieve final results.    
     
     
         8 . A method for sharing, storing and managing mass video data in a video geographic information system, which is characterized in establishing database by sharing and storing mass video data corresponding to spatial geographic information, the method comprising the steps of:
